A mountain biker died after following hospitalization for heat-related symptoms after the cyclist stopped to help dehydrated hikers, according to a local NBC affiliate. 

On Saturday, the Cal Fire San Diego received a call about four hikers with dehydration and heat-illness-related symptoms, near Jacumba. The hikers did not have food or water,  according to Cal Fire spokesperson Mike Cornett.

When police arrived, a group of mountain bikers helped lead firefighters and a rescue helicopter to where the hikers were located in the remote area, according to a Facebook post. 

“A huge thank you to the bystanders that were able to lead the firefighters and rescue helicopter in to where the patients were,” said the post. 

Six people, including two of the mountain bikers, were treated at the scene. One cyclist was taken to a hospital, where they were pronounced dead later that day. 

The Cal Fire department warns against hiking in the extreme heat, especially in peak daytime hours. They recommend bringing food and water, hiking in a group and letting friends and family know of your location.

In Jacumba Saturday, the highest temperature was 106 degrees Fahrenheit, according to AccuWeather.
